This is on a Samsung ChromeBook Plus (CB+) under Crostini … Perhaps another repo can be assigned with apt-get?

Yes! However it is worth noting that it has an ARM processor … so there needs to be an arm64.deb build, not just the existing i386 & AMD64 builds.

i tried to open a separate thread asking for this but it was deemed a duplicate of this thread… So this thread takes on the task of asking for an ARM build.

i should note that the Asus CB+ was the first CB to receive a Crostini build – after the PixelBooks. Prolly due to the very recent Linux Kernel. Many CB’s will be left behind because of their too old Linux Kernel.

Though Atom doesn’t officially support Chrome OS, a GitHubber did just post about successfully running Atom on Chrome OS: blog<.>atom<.>io/ 2018/10/02/running-atom-on-chome-os.html

Crostini is just a shell: the actual OS i the same Debian build that runs Chromium.
